To all whom t may concern:

Be it known that I, MYRON J. CAswnnLfa citizen of the United States of America, residing at Sandusky, in the county of Erie and State of Ohio, have invented certain new and useful Improvements in Spraying Apparatus, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to improvements in spraying apparatus for spraying trees, vines, dac., with a liquid for thepurpose of removing insects or other injurious life; and its object is to provide a pump adapted to be attached to the head of a barrel or other receptacle for the liquid with a'cylinder extending into the barrel and having an upper open end to catch the drip, atubular plunger-rod extending into the cylinder and provided with a piston-head in which is a valve to admit the liquid into the plunger-rod, and an air-chamber in the upper endl of said plunger-rod to :insurev a steadyflow, and to provide said pump with certain hother new and useful features whereby a device which is cheap,

l durable, simple in construction, and efficient in its operation is securedfall as hereinafter more fully described, and'particularly pointed out in the claims, reference" being had to the accompanying drawings, in which- Figure 1 is a side elevation of a device embodying my invention attached to a barrel, which is partially shown in section. Fig. 2 is a sectional view of the same on the line 2 2 of Fig. l. Fig. 3 is an enlarged sectional detail of the lower end of the pump cylinder and piston. Fig. 4 is an enlarged sectional detail of the upper end of the tubular plunger-rod.

Like letters refer to like parts in all of the figures.

As shown inthe drawings, A `is a barrel to hold the liquid, and B a casting secured to the headof the'barrel' andprovided with the stand C, to which'is pivoted the pump-handle D. In the casting B is an opening B', into which is screwed the cylinder E, the upper end of said cylinder beingopen and the lower end closed by a cap E', into which cap is screwed the pipe F, leading to the bottom of the barrel. On the lower end of the pipe F is secured a casting G, provided p with a strainer and having downwardly-projecting lugs to engage the bottom of the barrel. A tubular plunger-rod I-I extends into the upper open end of the cylinder E and' is provided `at its lower end with a piston-head J, consisting of the enlarged end J of the rod, which is externally screw-threaded to en gage the sleeve J2 and internallyscrew-threaded to engage the cap J 3, said sleeve and cap being provided with flanges to engage and hold the packing-ring J4. Within the enlarged end J of said rod is a Valve I, provided with a stem I', extending through the cap J3, the upwardly-extended flanges of said cap furnishing a seat ,for said valve, and a nut on the lower end of said stem limits the movement of said valve. In the cap J3, around the said stem, are openings to admit the waterto said valve.` A valve-seat is formed on the capE, and a valve K provided to close the upper end of the opening to the pipe F, said valve Kibeing limited in its movement by the aperturedcap K'.

On the upper vend of the plunger-rod H is securedthe cylindricalair-chamber L, which is providedto insure a steady iiow of the liquid, and said plunger-rod near its upper end is provided with a T or branches M, leading in opposite directions, for the attachment of a hose N, the branch not in use being closed by a cap N.

The casting a, which forms a part of the handle D, is made in halves to embrace the stand C and plunger-rod H and is pivoted to the latter by being provided with openings adapted to receive the branch pipes M and T `to the former by a pivot-pin O, adapted to engage the openings b or c in said. stand and correspondingopenings in the end of the casting a. The handle is thus provided with two points of attachment to the stand, said pin being inserted in the opening c, as shown, when the stroke of the handle is short.` The lopening b is nearer the top of the stand O and farther from the rod II than the opening c, and when the stroke is long the pin O' should bemoved to that opening, so that the rod will travel more nearly in alinement with the axis of the cylinder E than it would if but one pivot were provided, making the length of lever between the pivot and point of attachment to the rod fixed and the same for all lengths of stroke. The stand C is also extended longitudinally between the sides of the handle portion a to form a guide for the handle and prevent the rod H from being moved laterally out of the axis of the cylinder E. The grip portion d of the handle is adjustably attached to the portion a by providing thesame with a casting e, having a divided socket to receive the handle, the parts of said casting being held by bolts passing through the same, and on said casting is aserrated head f, extending between the sides of the portion a, which sides are also serrated to interlock with the serrated portion of the head, and a bolt g, passing through the sidesA and head, forms the pivot and binds the parts together.

If there is any leakage around the hose when it is attached to the branch M, the liquid thus escaping will fall into the upper open end of the cylinder E, and to allow such accum ulation to flow back into the barrel I provide openings O near the top of the cylinder; but at times it may be desirable to incline kthe barrel or lay it on its side, in which case the liquid would escape from this opening, and so to prevent I this I provide a cap P, faced with leather or other suitable material, to cover said openings, said cap being held and adjusted thereover by a thumb-screw journaled in the casting B and screw-threaded at its lower end to engage a screw-threaded opening in said cap.

Q is a bracket secured to the chamber L, to the outer end of which bracket is attached a rod R, extending through the head of the barrel and provided at its lower end with a blade S to agitate the liquid.

What I claim as my invention is l. In a spraying apparatus, a cylinder, a valve in the bottom of said cylinder, a hollow plunger-rod, a piston-head on the lower end of said rod, a valve to close the lower end of said rod, oppositelyextended branches forming a T at the upper end of said rod and forming a place of attachment for a hose, a divided handle embracing the rod and having openings to receive the branch pipes of the T, and a stand to which said handle is pivoted.
